Many texts cite the normal resting adult human heart rate range from 60–100 bpm.[1]Tachycardia is a fast heart rate, defined as above 100 bpm at rest. Bradycardia is a slow heart rate, defined as below 60 bpm at rest. Several studies, as well as expert consensus indicates that the normal resting adult heart rate is probably closer to a range between 50–90 bpm. During sleep a slow heartbeat with rates around 40–50 bpm is common and is considered normal. When the heart is not beating in a regular pattern, this is referred to as an arrhythmia. Abnormalities of heart rate sometimes indicate disease.

YOU ONLY HAVE ONE HEART

We take our Heart rate for granted.

We treat it badly in a lot of ways by eating the wrong foods, lack of the right exercise etc. We only have one heart so look after it. Poor heart conditions can be in your genies and I know as my wife and her blood relations have not lived long in the past. Due to medical improvements doctors are keeping heart problems under control when monitored properly like my wife is.

WITHOUT IT NO FUTURE

Monitoring heart health should start early in life regardless of age as you only have one. The heart never recovers fully from any health problems so do not try to find out the hard way if you are bullet proof. In 1977 my uncle a DOCTOR went to get out of bed one morning and DIED at a young age of nearly 50 years old.
